I already demonstrated it in my original post.

I'm not sure why there is confusion here. By definition, an admin  
user is a user with an admin name and password.

Then you aren't an admin user. You're using someone else's admin  
account. This is not simply arguing over semantics. These concepts  
are well defined on Unix-based systems.

Of course it makes a difference. Security has everything to do with  
trust.

If your argument is based primarily on allowing others to have access  
to an admin account which is not theirs (i.e., for which they do not  
have the password), then you really don't have much of an argument.  
In general, this is a VERY BAD IDEA, and is completely unnecessary on  
a multi-user system like OS X.
